I always carry a #3 Black Fury spinner with me when trout fishing. I don’t use the lure often even though I have a lot of faith in it. I’ve caught a lot of trout on this and smaller versions over the years. It was all I used on the Baldwin River when I first started spin fishing – it was that dependable.
Now I use it when I need something magical, something that makes no sense, something the trout won’t recognize but want to attack. The stream conditions and topography have to be right. I mainly use it for deep pools and runs. If the water is stained and the stream flooded, that is a bonus. The lure sinks out of sight, down where big trout hold in deep water, and can be reeled in slow because of the large blade. There is no second guessing when a trout hits it. They smash it. The single treble hook does its job – the trout stay on until landed.
Sinking out of site means you can lose the lure on hidden logs and branches. If you do get hung up, wade upstream of the snag as far as possible to leverage it off.
I also carry plain gold and silver spinners in various sizes which must look like the scales of small fish glittering in the stream. On bright days and clear streams, the glitter can entice trout out of cover even though the fish may be smallish.
Mepps also makes a version with a bucktail but I prefer no tail for trout. For Pike fishing, I think a bucktails adds to the attraction. For trout I think the bucktail looks unnatural, though it is impossible to understand what they consider natural considering they attack Black Fury lures. I have no idea what this lure represents to them.
